UPDATE my own thread.
Finally had enough time to work on my "project" for several hours in a row.
Had to dig approx. 3 feet further towards the house and 3 feet down. Fortunately at this point the water line was clear of the incredible mass of roots. Looks like I was lucky for a change. The break in the water line appears to have been caused by the levering effect of the root mass it was passing through.
There was a small stress crack on the top of the line where the roots were really tweaking the pipe. I cut the pipe off as close to the root bound section as possible and installed a "patch" section about 3 feet long. Took a bit of wrestling to get the patch to align with the rest of line. I had to run it in a loose curve above the mass of roots. I used irrigation style barbs and double clamps to install the patch. If I went with brass or the standard poly barbs they would have been to long to accomadate the bend/twist in the patch section. Had to tap the barbs into the existing pipe ends with a soft block of wood the forced the patch ends onto the barbs, they didn't want to sit square to the shoulder.
My son had to hold the patch in place will I clamped down the patch section. The nice thing about the irrigation barbs is they are a bit shorter than standard barbs, have a nice shoulder in the center, and I think they are slightly flexible, which enabled the patch section to be clamped to the barb in a circle instead of an oval, the longer barbs would have levered the pipe away from the barbs.
I thought they were going to blow apart when we turned on the pump, but knock on wood, no leaks as of this AM, approx. 12 hours since the splice was installed. Waiting for the next weak spot to spring a leak now that this leak has been addressed.
Now that I have regular water service for the wife and girls I can remove the giant root mass and lay the pipe flat in the trench. I plan on digging a new trench during the summer and placing the power feed and water line in a larger pipe or conduit.
Will take some pics and post them to the photo section this evening, never could get the SnapFish photo links to work out the way I wanted them to.
Thanks for all the good advice,
Dave
